OXNARD, Calif. -- Dallas Cowboys backup quarterback Kellen Moore suffered a broken right leg in Tuesdays practice, which puts even more stress on a position many believed needed help behind Tony Romo already.On what was scheduled to be Moores second-to-last team snap of practice Tuesday, guard Jared Smith was pushed back by defensive lineman Lawrence Okoye and stepped on Moores right ankle as the QB was making a throw to the sideline. Moore remained on the ground for a bit before he was able to limp off. He was helped to a trainers table and later carted to the locker room with an immobilization splint on his right leg.After practice, owner and general manager Jerry Jones said the initial diagnosis was a broken leg, and Moore would get X-rays at a local hospital. Jones was unsure whether Moore would require surgery and how much time he would miss.A source said Moore suffered a broken right fibula and will need surgery. He is looking at a two- to three-month recovery, depending on surgery findings, according to a source.Its regrettable, and well basically just take a look at it and address it there, Jones said. I dont have any comments about what, if anything, well be doing there.With Romos recent injury history, the backup position is ultra-important to the Cowboys. Romo, who turned 36 in April, missed 12 games last season because of a twice-broken left collarbone. He had two back surgeries in 2013. The Cowboys went 1-11 with Brandon Weeden, Matt Cassel and Moore starting games in Romos absence to finish 4-12 last season, their worst finish since a 1-15 mark in 1989.The Cowboys have backed Moore as Romos backup throughout the offseason. He played in three games last season, started the final two and finished with four touchdown passes and six interceptions. In the season-ending loss to the Washington Redskins, he completed 33 of 48 passes for 435 yards with three touchdowns and two interceptions.In free agency, the Cowboys did not go after high-priced backups such as Chase Daniel and Colt McCoy, but they met with veteran Matt Moore, who opted to remain with the Miami Dolphins. Last week, Jones said veteran Nick Foles was not an option, mostly because the Cowboys have four quarterbacks on the roster. With Moores injury, that could change.Rookie Dak Prescott took the second-team snaps after Moores injury. The Cowboys selected Prescott in the fourth round of the draft. He was the first quarterback drafted by the Cowboys since 2009.Its an opportunity for me to take more reps, get more snaps, and its something Im going to come in and make sure Im ready for, Prescott said. Im going to go study this film and continue to study it ... and take everything from the film room what Ive learned and take it to the field.Undrafted free agent Jameill Showers is in his second year and has been sharing the third-team work with Prescott.Moore had waited five years to be in a position to be the No. 2 quarterback after a record-setting career at Boise State. He spent four seasons with the Detroit Lions after making the team as an undrafted free agent but did not play in a game. It was his connection with Scott Linehan there that led him to the Cowboys last summer, first on the practice squad and then on the active roster.He spoke over the weekend about the excitement of the opportunity, but now he has to deal with a broken leg.Your heart hurts for him because he just works really hard, tight end Jason Witten said. Hes constantly taking notes. Hes studying. Hes communicating. And at that position -- Ive seen it with Tony for a long time as we came in -- you never know when your [opportunity] is going to happen. Hell continue to fight. Thats what he is. Thats who hes been his whole life. Hell bounce back, Im sure.Information from The Associated Press was used in this report.Max Garcia Jersey .

Logan Jersey . - Chris Tierney snapped a tie with a power-play goal late in the third period as the London Knights rallied from a 3-0 deficit to beat the Erie Otters 5-3 in Ontario Hockey League action on Wednesday.CHICAGO -- Moments after his successful return to Chicago with the U.S. national team, Jimmy Butler pulled on a T-shirt with a picture of Brazilian soccer star Pele on the front.Yup, its almost time.Kyrie Irving scored 13 points, DeMarcus Cousins powered a dominant performance in the paint, and the United States pulled away from Venezuela for an ugly 80-45 exhibition victory Friday night.Coming off three straight flashy victories in Las Vegas and California, the United States used a strong fourth quarter to shoot 42.4 percent from the field in by far its worst offensive performance of its five-city tour in preparation for the Rio Olympics. But the Americans used their superior athleticism to limit Venezuela to 24 percent shooting and owned the interior with a 54-29 rebounding advantage.Quite frankly, Im very pleased about tonight because you dont just want to just hit 17 3s and not work hard, U.S. coach Mike Krzyzewski said. We had to work real hard tonight.Butler, a two-time All-Star with the Bulls, had four points and eight rebounds in 21 1/2 minutes in his first start with Team USA. He was cheered every time he was announced at the United Center.This is like home for me now, Butler said. Im glad that I got to play here for USA in front of my hometown crowd. Theyve embraced me since Day 1. I hope they continue to do so. I want to win with the Bulls. I want to win with USA and bring a championship with the Bulls and a gold medal here.Butler had one of the few electric plays for the U.S. when he ran out on the break and dunked Kyle Lowrys tip pass in the fourth quarter. DeAndre Jordan also had a vicious dunk off a lob from Kevin Durant, and DeMar DeRozan drew chants of USA! USA! with a windmill jam in the final minutes.Klay Thompson also scored 13 points, and Cousins finished with seven points and 12 rebounds. Durant had nine points of 3-of-9 shooting for the U.S., which plays one more exhibition on Monday against Nigeria before departing for Brazil.We just kept fighting defensiveely, and we were great (in that area), Durant said.dddddddddddd And in the second half, we made some shots.John Cox scored 14 points for Venezuela, which will play the U.S. again on Aug. 8 in the Olympics. Nestor Colmenares pulled down 10 rebounds.Their defense is so good because they can switch everything because of their length and athleticism, Cox said. So theres not really another team in the Olympics that can do that.Irving and company were greeted with a round of hearty cheers when they came out for pregame warmups. Fans flocked to the side of the court where the Americans had their layup line, and Anthony and Durant posed for pictures with a couple of eager boys.Before Butlers introduction drew the most applause of the night, former Chicago coach Tom Thibodeau received a thunderous ovation when he was announced with the U.S. coaching staff. Thibodeau took a year off after he was fired by the Bulls in May 2015, and then was hired as Minnesotas coach and president of basketball operations in April.Hes the best as far as preparation and team player and whatever, and the fans appreciate it, said Krzyzewski, a Chicago native. It was great. I love the fact that my town gave a guy who gave them his heart and soul for the number of years hes been here, and acknowledged that. Thats a great, great thing.The star power also extended to the sideline near the U.S. bench, where former Olympians Scottie Pippen and Dwyane Wade watched the action attentively. Wade was joined by his wife, actress Gabriel Union, hours after he held his introductory press conference for his new contract with his hometown Bulls.Pippen played on the 1992 Dream Team that rolled to gold in Barcelona, and also helped the U.S. win gold in 1996. Wade was on the Americans gold medal-winning teams at each of the last two Olympics.---Jay Cohen can be reached at http://www.twitter.com/jcohenap[url=http://www.authenticwholesalejerse last two Olympics.---Jay Cohen can
